[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The following first describes the concepts involved in the present application in conjunction with the accompanying drawings. It should be noted that the following description of each concept is only to make the content of the present application easier to understand, and does not limit the scope of protection of the present application; at the same time, the embodiments and features in the embodiments of the present application can be combined with each other in the absence of conflict. The present application will be described in detail with reference to the accompanying drawings and in conjunction with the embodiments.

[0024] like Figures 1 to 6As shown, the present invention provides an embodiment of a multifunctional auxiliary maintenance device for a heavy-duty mining car bucket, including a base 21, a support frame 7, a positioning mechanism 1, an inner support mechanism 2, an outer support mechanism 3, a local support mechanism 4, a first electric telescopic rod 5 and an angle adjustment mechanism 6. The positioning mechanism 1 includes a slider 8 and a clamping seat 9. There are multiple sliders 8 and clamping seats 9 corresponding to each other. The slider 8 is slidably mounted on the support frame 7. The clamping seat 9 is fixed at the bottom of the slider 8. The clamping seat 9 can be clamped at the top of the side wall of the bucket. The first electric telescopic rod 5 is fixed at the top of the slider 8.

[0025] When it is necessary to clamp the compartment at different positions, the positions of the inner support mechanism 2 and the outer support mechanism 3 can be adjusted by moving the position of the slider 8, so that the inner support mechanism 2 and the outer support mechanism 3 can clamp the side wall of the compartment from different positions, avoiding the inner support mechanism 2 and the outer support mechanism 3 from blocking the part to be welded.

[0026] The outer supporting mechanism 3 includes an outer clamping arm 10, and the inner supporting mechanism 2 includes an inner clamping arm 11. The middle part of the inner clamping arm 11 and the middle part of the outer clamping arm 10 are respectively hinged to the two sides of the slider 8. The upper ends of the inner clamping arm 11 and the outer clamping arm 10 are fixed with a pressure rod arm 12. The pressure rod arm 12 is provided with a waist-shaped hole 13. The top end of the first electric telescopic rod 5 is slidably connected with the waist-shaped hole 13 through a transverse axis 14. The inner clamping arm 11 and the outer clamping arm 10 are used to clamp the box bucket. When the first electric telescopic rod 5 is extended upward, it can push the transverse axis 14 to slide along the waist-shaped hole, thereby pushing the upper ends of the inner clamping arm 11 and the outer clamping arm 10 to move, and under the action of the lever, the lower ends of the inner clamping arm 11 and the outer clamping arm 10 move toward the side wall of the box bucket to clamp the side wall of the box bucket.

[0027] There are multiple outer clamp arms 10, which are mirror-symmetrically arranged on the outside of the compartment. A clamp head 29 is hinged at the lower end of the outer clamp arm 10, and an anti-slip groove is arranged on the surface of the clamp head 29.

[0028] There are multiple inner clamp arms 11 corresponding to the outer clamp arms 10, and the multiple inner clamp arms 11 are arranged on the inner side of the compartment in a mirror-symmetrical manner. The lower ends of the inner clamp arms 11 on two opposite sides are slidably connected by an arc-shaped pressing groove 30, and the arc-shaped pressing groove 30 can fit with the bottom of the compartment.

[0029] The local support mechanism 4 includes a support slide rod 15, a clamping seat 16 and a clamping screw 17. The support slide rod 15 is slidably connected to the outer clamp arm 10 through a rod seat 18. The clamping seat 16 is slidably installed on the support slide rod 15. The clamping screw 17 passes through the clamping seat 16 and is threadedly connected to the clamping seat 16. The angle adjustment mechanism 6 is used to adjust the angle of the support frame 7.

[0030] The local support mechanism 4 also includes a fixed seat 19 and a second electric telescopic rod 20. The fixed seat 19 is fixedly connected to the support frame 7. One end of the second electric telescopic rod 20 is rotatably connected to the fixed seat 19, and the other end of the second electric telescopic rod 20 is rotatably connected to the middle of the support slide bar 15.

[0031] When a crack occurs somewhere on the side wall of the box, the height of the support slide bar 15 is adjusted by the second electric telescopic rod 20 to make the support slide bar 15 close to the crack, and then the clamping seat 16 on the support slide bar 15 is moved to the crack. When the outer clamping arm 10 is clamped, the clamping screw 17 is rotated to make the clamping screw 17 contact the box near the crack, and the clamping screw 17 is continued to be rotated to adjust the pressure of the clamping screw 17 on the box, thereby supporting the metal plates on both sides of the crack and reducing the deformation caused during the welding process.

[0032] The angle adjustment mechanism 6 includes a lifting seat 22 and an electric turntable 23. The lifting seat 22 is fixed on the base 21. The lifting seat 22 is used to drive the electric turntable 23 to move up and down. Both ends of the support frame 7 are connected to the electric turntable 23. The electric turntable 23 is used to drive the support frame 7 to rotate.

[0033] Before clamping the bucket, the support frame 7 is lifted by the lifting seat 22, and then the bucket is moved to the bottom of the support frame 7. Then the lifting seat 22 descends, causing the outer support mechanism 3 and the inner support mechanism 2 to descend to the bucket to clamp the bucket. After clamping, the lifting seat 22 drives the support frame 7, the outer support mechanism 3 and the inner support mechanism 2 to rise to the highest point together, so that the bottom of the bucket is suspended in the air, so that the angle and posture of the bucket can be adjusted later, which is convenient for repair and welding of the bucket.

[0034] The angle adjustment mechanism 6 also includes an arcuate slide rail 24, an arcuate rack 25, a sliding seat 26, a worm gear device 27 and an adjusting motor 28. The middle part of the arcuate slide rail 24 is fixed on the electric turntable 23, the arcuate rack 25 is fixed on the inner ring of the arcuate slide rail 24, one end of the sliding seat 26 is rotatably connected to the support frame 7, the other end of the sliding seat 26 is slidably connected to the arcuate slide rail 24, the worm gear device 27 is installed on the sliding seat 26, the worm wheel of the worm gear device 27 is meshed with the arcuate rack 25, the worm of the worm gear device 27 is coaxially fixedly connected with the output shaft of the adjusting motor 28, and the adjusting motor 28 can drive the sliding seat 26 to move along the arcuate slide rail 24 through the worm gear device 27.

[0035] The working principle of the angle adjustment mechanism 6 is as follows: when it is necessary to flip the compartment to the bottom facing upward, the electric turntable 23 is directly used to drive the arc slide rail 24 and the support frame 7 to rotate, so that the compartment can be flipped to the bottom facing upward, and the electric turntable 23 can also stop at any position during the rotation process, so that the compartment can be flipped to any angle for welding operation. After the flipping angle adjustment of the compartment is completed, the compartment is driven to descend by the lifting seat 22 to reduce the height of the compartment, which is convenient for welding at a higher position of the compartment; in addition, if it is necessary to weld one end of the compartment near the inner bottom, the compartment is directly flipped to the bottom facing upward. When welding, it is necessary to drill under the compartment to operate, which is very inconvenient, because the two ends of the support frame 7 are Both ends are connected with sliding seats 26 and arc-shaped slide rails 24. At this time, the adjusting motor 28 drives the sliding seats 26 at both ends to move along the arc-shaped slide rails 24 through the worm gear devices 27 at both ends, and the sliding seats 26 at both ends of the support frame 7 move in opposite directions, that is, the sliding seat 26 at one end of the support frame 7 moves upward and the sliding seat 26 at the other end moves downward, which can drive one end of the compartment to be tilted and the other end to be pressed down, so that the compartment as a whole presents an inclined posture, so that the end to be welded is in a lower position, which is convenient for welding and maintenance of the inner bottom of this end. The angle adjustment mechanism 6 cooperates with the electric turntable 23 and the arc-shaped slide rail 24 to adjust the compartment to a variety of postures, so as to facilitate welding and maintenance of various positions of the compartment.

[0036] A movable clamp 31 is provided on the inner wall of one side of the clamping seat 9, and the movable clamp 31 is connected to the side wall of the clamping seat 9 through a clamping bolt 32. Rotating the clamping bolt 32 can drive the movable clamp 31 to move closer to or away from the inner wall of one side of the clamping seat 9. The inner bottom of the clamping seat 9 is also rotatably installed with multiple supporting rollers 33 arranged parallel to each other.

[0037] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above are only preferred implementation methods of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the concept and technical solution of the invention to other occasions without improvement, should be regarded as the scope of protection of this application.
